Q:Do I really need to clean my fuel system? Why?A: If you need to save money - or just want to make sure you're not spending more than you have to - then cleaning your fuel system is a quick and easy way to do both. Cleaning your fuel system cost less than $40 per year and reduces fuel consumption by cleaning the deposits that routinely clog fuel injectors and distort the fuel spray patterns, decreasing fuel flow and efficiency. It also removes the moisture which tends to build up in your fuel system, reducing the likelihood of expensive injector repairs.Q: Is the Common Rail Diesel System Clean & Protect only for use in vehicles with common rail high pressure injection systems? A:No, CRDSC&P is “backward compatible” with all diesel engine vehicles. All diesel fuel system types can be cleaned and also importantly, reap the benefit of moisture removal. The technology behind the safe water removal was specifically targeted at Common Rail High Pressure systems – hence the name of the product.

Q: The label says that Oxicat is sufficient for 15 gallons of fuel. My tank holds less than 14 gallons - can I still add the Oxicat?A: ​It's not recommended for Oxicat to be added to too small an amount of fuel because of the way the product is designed to work post combustion. Unlike a traditional "fuel system cleaner," Oxicat works once the fuel has gone through the engine (when combustion takes place) and is on its way out via the exhaust system. This is the point at which Oxicat cleans the built-up contaminants. We suggest adding to the tank at fill-up with between 12 gallons (minimum) and the amount stated on the can of 15 gallons / 60 liters.
